Samsung Electronics has maintained its number one position in the world TV market for ten years. The electronics giant will unveil its next TV model, a Quantum dot light emitting diode (QLED) TV which the company expects to lead the TV market for the next ten years. According to the TV industry on August 31, Samsung Electronics will explain the strengths of its QLED TV technology and sketch out its QLED development roadmap in a meeting with reporters at the IFA 2016 on September 1 (local time).
A QLED is a display based on semiconductor crystals (quantum dots or QDs) which are 2 to 10nm (1nm is a billionth of 1 meter) and emits light on their own. A quantum dot has an advantage of showing a desired color only by controlling the sizes and shapes of its particles.
Moreover, like an OLED, a quantum dot can emit light on its own, making back lights obsolete and towers over an OLED in energy efficiency and color reproduction.
The TV industry is paying a lot of attention to a QLED’s possibilities. C-Net, an IT-specialized medium in the US, explained that an OLED TV shows colors in a manner similar to that of current LCDs but a QLED TV can express a wider color range than an OLED TV. As a QLED display has a design structure similar to that of an OLED display, a QLED display can be commercialized faster than an OLED display which took more than ten years to develop, C-Net said.
C-Net evaluated that a QLED display is a technology that can offer various strengths at the highest level in addition to excellent performances, a wide color gamut and lower power consumption. They forecast that a QLED TV will be launched after three to five years or faster.
“A QLED display is 30 to 40% better than an OLED display in luminance efficiency and halves power consumption compared to an OLED display,” said Trusted Review of the UK which assesses various products.
But some experts in the display industry say that quantum dots applied to current TV models are a non-conductive material that cannot emit light on its own and vulnerable to heat. Thus, they say that the commercialization of quantum dots will take some time.
